小米5.1系统运行正常，360的6.0系统出现内存泄漏

[1234511w]

一个界面（activity）,里面用一个viewpager，内容为两个fragment，其中一个fragment代码如下，
其实逻辑就是异步任务去加载数据，然后显示在listview中，中间有一个广播接收，我在ondestory中判断异步任务是否结束
没有结束就调用cancle，然后做广播接收器的注销，异步任务我都写在外面，用弱引用，不知道哪里会泄漏，360的6.0系统
退出该activity然后再进来，内存就比上次进来后增加了，每次都会增加，琢磨不透。有没有高手遇到过或解决过的？

既然是内存产生了泄露,最好先用mat之类的工具先看一下是由于什么持有了对象,导致无法释放,然后在程序里面找问题代码就好了.
